NSIS: Check that a command is on the PATH

Question

How can I check that a command line application is accessible from the PATH with NSIS?

In this particular case, I want to check if node is accessible from within the terminal.

I thought about executing > where node and comparing the result with INFO: Could not find files for the given pattern(s). however there might be a better way using NSIS functions.
